UL uses the MesoMap system which is a combination of two atmospheric models: a mesoscale numerical weather prediction model and a microscale wind flow model. The mesoscale model simulates weather conditions for a representative meteorological year on a horizontal grid of 2.5 km. The microscale model then refines the wind fields from the mesoscale model to capture the local influences of topography and surface roughness changes at a resolution of 200 m.
